ASTM D3278
FLASH POINT OF LIQUIDS BY SMALL SCALE CLOSED-CUP APPARATUS.
These test methods cover procedures for determining whether a material does or does not flash at a specified temperature (flash/no flash Method A) or for determining the lowest finite temperature at which a material does flash (Method B), when using a small scale closed-cup apparatus. The test methods are applicable to paints, enamels, lacquers, varnishes, solvents, and related products having a flash point between 0?°C and 110?°C (32?°F and 230?°F) and viscosity lower than 15?000 mm2/s (cSt) at 25?°C (77?°F).
